Victron MultiPlus-II 48/15000/200-100 Inverter

The Victron MultiPlus-II 48/15000/200-100 represents the absolute pinnacle of high-capacity power management, seamlessly merging a massive 15000VA true sine wave inverter, an advanced 200A adaptive battery charger, and an ultra-fast 100A AC transfer switch into a single, high-performance enclosure. Specially engineered for large residential properties, commercial enterprises, and heavy off-grid systems, this 48V powerhouse is designed to serve as the core component of a sophisticated Energy Storage System (ESS). It integrates flawlessly with external MPPT solar charge controllers or grid-tied PV inverters to deliver maximum self-consumption and total energy security.

Equipped with Victron's proprietary PowerControl and PowerAssist technologies, the MultiPlus-II intelligently optimises power distribution from limited AC sources. When shore power, grid supply, or an on-site generator is restricted, the unit automatically dials down its battery charging current to prevent an overload (PowerControl). Should peak demand surpass the source's capacity, the inverter instantly draws from the connected 48V battery bank to supplement the deficit (PowerAssist). This allows users to successfully run heavy loads—such as large workshops, industrial machinery, or multiple air conditioning units—without requiring an oversized grid connection or generator.

The unit features dual AC outputs configured for smart system efficiency. The primary AC output delivers seamless, no-break UPS functionality. In the event of a grid failure or sudden generator shutdown, the MultiPlus-II takes over the load in less than 20 milliseconds, ensuring that sensitive IT infrastructure, computers, and critical appliances continue running without a single hiccup. The secondary auxiliary output (rated at 50A) is active exclusively when AC input power is present, preventing non-essential, heavy-draw appliances like water heaters or underfloor heating from draining your battery bank during an outage.

Designed for professional-grade system expansion, the MultiPlus-II 48/15000 provides flexible scalability via its dual VE.Bus communication ports. Up to three identical units can be configured together for heavy-duty three-phase output configurations, making it an excellent match for commercial operations. Its robust steel enclosure features fan-assisted cooling and an IP22 protection rating, guaranteeing reliable operation across a broad temperature range. The system is fully customisable and compatible with leading managed lithium battery brands, ensuring long-term flexibility and seamless system monitoring when paired with a GX control device like a Cerbo GX.
